Originality, depth... these are things your driving at with this argument. We get it (that's why we're here, too).
Instead of asking someone to write up a new mineral or crazy tough tree, why not develop something through your character in game?
Konti make their daggers from shells. Akalaks fashion theirs from glassbeak horns. Why not use what's around you and do something through your posts?
If we had a staff of sixteen people or so, we could explore more avenues of expanding the game in the kind of directions you're suggesting but we don't. There's Goss, a behind-the-scenes Gillar and four other STs. We're all coming up with new things for our domains that players can use or ignore as they please but we also have a lot of admin work to do not to mention our own PCs.
I'm going to refrain from being an absolute jerk and not point out a handful of things that could stop this conversation in its tracks. Instead, I'm going to ask you to kindly leave this alone.
